BRACKET FOR MAGNIFYING INSTRUMENTS Filed May 1, 1930 2 Sheets-Sheet 2 Patented Feb. 23, 1932 UNITED STATES Wt! DEAN BROWN BECKER, OF FORT ATKINSON, WISCONSIN BRACKET FOR MAGNIFYING INSTRUMENTS Application filed May 1,

My invention relates to improvements in brackets for magnifying instruments.

The object of my invention is to provide a support for a magnifying instrument such as a microscope or binocular whereby to perunit of its use in conjunction with a machine including microscopically small parts in operation so that the operator of such a machine may swing the magnifying instrument Pi to and from the Zone in which said parts are operating and thus permit such operator to observ faulty operation or enable him to make repairs more quickly and accurately than heretofore possible.

Another object of my invention is to so construct a universal mounting in connection with the support above referredto so that the operator may with facility ad ust, move or completely displace the magnlfying instrument.

in the drawings: Figure 1 is a perspective of a full fashion knitting machine in which my invention has been incorporated.

Figure 2 is an isometric view of the same machine shown in Figure l with my 11nprovcd support swung to inoperative pos1- tion.

Figure 3 is a detail side view of my magnitying instrument and mounting.

Figure 1 is a perspective of a modified form of mounting.

Like parts are identified by the same reference characters throughout the several views.

" a large number of knitting needles which have very small beards and curved portions which may be worn or nus-aligned so as to affect the operation of the machine. It will be understood from the description hereinafter contained that the support for the mag- 1930. Serial No. 448,870.

nifying instrument which I provide with the knitting machine may be also used in slightly altered form in many other machines where very small parts must be observed.

The knitting machine which I have shown in the drawings includes frame members 10 comprising castings which are spaced from one another and provided with apertures through which tubular members, such as the stretchers 11, 12 and 13, extend to complete a long frame assembly upon which the bed 1st and other parts of the knitting machine are supported. As indicated in the drawings a large number of needles 15, arranged in a row above the bed 14, are in constant opera tion while the machine is at work and threads of yarn or silk 16 fed through the needles 15 must be provided with a smooth uninterrupted course of travel through the machine if its operation is to be acceptable. However, in the ordinary operation of the machine, small beards forming part of the needles 15 or portions of the curved operating head of the needles may become bent or misplaced so that the smooth operation and the smooth course of travel above referred to are inter ferred with. Heretofore, in the operation of the machines, the operator has been compelled to trace broken threads or use other expedients to discover which of the many needles is causing trouble. Much difliculty has heretofore been found and much time has been lost in locating the offending part.

In the use of my improved structure, however, I have provided a binocular 17 which must, when in operation be positioned as indicated in the drawings directly in front of the needles and in a position where its con tinued disposition at that point during the operation of the machine would be decidedly disadvantageous. I therefore provide brackets 18 pivotally mounted upon the stretcher 13, and by which a bar 19 is supported. And upon the bar 19 a slide 20 is so constructed as to permit reciprocation thereof along the entire length of the knitting machine.

Upon the slide 20 I supportan arm 21 which is so constructed as to conform to the usual shape of a universal mounting 22 such as is commonly used for the support of a microscope for laboratory use. At 23 upon this mounting I provide an apertured boss to which a bifurcated segmental leg 24 is adjustably connected. And upon the leg 24: the binocular 17 is secured. 7

At 25 I provide a rod which comprises an adjustable stop having threaded engagement with a plate 26 upon bracket 18, whichen ables the user of my improved construction to position the bar 19 at the. proper height so that the binoculars are within easy range of adjustment. The lower end of the stop rod 25 bears upon frame member 10 when in binocular supporting position.

As stated above, the brackets 18 are pivotally mounted upon the stretcher 13 and, as indicated in Figure 2, the entire supporting device for my binoculars may be swung pivotally to the position indicated in Figure 2, whereupon the knitting machine is in full vision and microscopic examination of small parts thereof is unnecessary.

In Figure t I have shown an alternative construction for accomplishing substantially the same purpose as the construction heretofore described. The essential difference between the construction shown in Figure 4 and 21 so that the binoculars may be swung upwardlyto an inoperative position when they are not needed instead of downwardly as provided in the constructions shown in Figures 1 and 2.

I have not minutely described the universal bracket and slide mechanism included in the part heretofore designated 22 since any device for providing a universal connection between the rod 21 and the binoculars would be satisfactory and many 'micrometer adjustments have heretofore been devised as mountings for magnifying instruments and may be used in my device. It is of importance, however, that the bar 19 be adjustably secured to parts of the frame of any machine to which my device is applied, and provision for a stop such as the rod 25 for adjustably positioning the bar for final disposition in relation to the work is important.

I claim:

1. In combination with a frame member, a support for magnifying instruments including a bracket pivotally connected at one end to said frame and having a stop adjacent its other end arranged to be moved into and out of engagement with the frame when the bracket is swung about its pivot, a longitudinally extending bar connected to said bracket, a slide movably mounted on said bar,

and means connecting the slide to the magnifying instrument.

2. In combination with a pair of spaced members, a support for magnifying instruments including a bracket pivotally connected to one of said members and having a stop arranged to be moved into and out of engagement with the other of said members, a longitudinally extending bar connected to said bracket, a slide movably mounted on said bar, and means connecting the slide to the magnifying instrument.

3. In combination with a pair of spaced members, a support for magnifying instru ments including a bracket pivotally connected to one of said members and having a depending adjustable stop arranged to be moved into and out of engagement with the other of said members, a longitudinally extending bar connected to said bracket, a slide movably mounted on said bar, and means adjustably connecting the slide to the magnifying instrument.

4. In combination with a pair of spaced members, a support for magnifying instruments including a bracket pivotally connected to one of said members and having a depending adjustable stop arranged to be moved into and out of engagement with the other of said members, a longitudinally extending bar connected to said bracket, a slide movably mounted on said bar and hav ing a laterally extending portion, and means adjustably connecting the magnifying instrument to said portion whereby the magnifying instrument is moved bodily with the bracket into and out of its operative position.
